Brown University student missing

RHODE ISLAND -- A Rhode Island student has been missing for nine days.

Police say Sunil Tripathi, 22, was last seen on campus March 16.

Even the FBI is involved searching several different states. Connecticut, New York, and Pennsylvania are all being searched.

His brother says they will not give up until they find some answers.

"We're still very hopeful and, you know, the Providence Police Department is still very much actively investigating this case and is still encouraging us to be very positive," said Ravi Tripathi, Sunil's brother.

Police have also spent the past week chasing tips. None of them have been successful so far.
